 My only test case besides the Chicken manual is quite small: about 2.3MB
 of wiki content, divided in about 160 files, which seem to be parsed in
 2-3 seconds on my system. The Chicken manual is about 1.8MB currently.

 I've taken a random sample from the wiki contents to test qwiki with, and
 I noticed that especially the page for 9p (eggref/4/9p) is extremely slow.
 I just tested this and it turns out that it takes about 13 seconds to
 generate the full html page:

 {{{
 #;7> (time (qwiki-update-file! '("9p")))
   14.809 seconds elapsed
    5.268 seconds in (major) GC
  2603950 mutations
      212 minor GCs
      194 major GCs
 }}}

 I was wrong thinking it was all caused by wiki-parse, though!

 {{{
 #;2> (time (call-with-input-file "/tmp/qwiki/9p" wiki-parse))
    0.969 seconds elapsed
    0.025 seconds in (major) GC
    16028 mutations
     1522 minor GCs
        1 major GCs
 }}}

 I think one second for parsing is a bit on the slow side, but acceptable.

 zbigniew: it turns out svnwiki->sxml is faster, not slower (on this
 particular file) than wiki-parse :)

 {{{
 #;4> (time (call-with-input-file "/tmp/qwiki/9p" svnwiki->sxml))
    0.24 seconds elapsed
    0.016 seconds in (major) GC
     7161 mutations
     1085 minor GCs
        1 major GCs
 }}}
